of course it is
more than 50% of communication is body language.
and then you have to add behavioural changes to that 50% as well.
plus they knew there was a shifter around.
meanwhile the shifter (who didn't know either well) could spot in about 10 secs via body language that huey/MM were trying to hide that they knew shifter was fake.
yet huey was bouncing shifter from the windows to the walls for 20 days before figuring it out.
We can agree to disagree on what the characters should have known, what they should feel and all that I’m through debating it.
But I’m objectively saying that we are not supposed to pick up on what he knows throughout the process. Like down to a level of writing my guy; I’m not even talking hypothetical situations anymore. Do you understanding the reason they showed the scenes that he referenced at the end?
If you don’t like the way they did it, that’s subjective and nobody can argue your opinion on the quality, but there was a clear process on how they wanted the situation to unfold to the viewing audience. I’m objectively telling you hughie picked up on what you are thinking he didn’t. The show literally spells it out directly. Did you think the nikka was just lying bringing up the keys scene and all that, or what? If you thought he should have put the pieces together and immediately said she was a clone…. You got it.
And maybe she misspoke but Starlight said a week and a half, not 20 days.
